Product Profile of Three Phase Numerical UV/ OV Protection Relay
Three Phase Numerical UV/ OV Protection Relay provides 3 Phase start connected, full under / over voltage protection and enables latching of fault value. The Numerical UV/OV Protection Relay is designed to meet the demand of low and medium switchgear control. Ashida Eletronics Pvt. Ltd., an ISO 9001:2008 accredited company is manufacturing Three Phase Numerical UV/ OV Protection Relay.
Ashida Eletronics Pvt. Ltd. supplies a wide range of electrical power protection relays, auxiliary protection relay and SCADA systems. The Three Phase Numerical UV/ OV Protection Relay is based on micro processor controller to perform powerful Digital Algorithms to find out Amplitude of voltage signal and then this value is used for protection and metering function.
